str::get isn't overflow-checked with InclusiveRange #42401
Description
Repro: https://is.gd/lVsdTA
#![feature(inclusive_range_syntax)]
#![feature(str_checked_slicing)]
fn main(){
println!("{:?}", &"hello".get(...usize::max_value()-1)); // None
println!("{:?}", &"hello".get(...usize::max_value())); // Some("")
}(The latter with [] correctly panics with "attempted to index str up to maximum usize".)
